Title: Sealing device
Inventor: YASUTOMI TAKAAKI
IPC: F16J15/18
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To improve durability and quality of a seal ring by lowering the corotating rate of the seal ring and one member in a sealing device. SOLUTION: Oil is led to a sliding face 21 by communicating grooves 41, and oil is circumferentially led by a circumferential groove 42 communicating the communicating grooves 41 circumferentially. Oil is further spread all over the sliding face 21 by fluid retaining grooves 43 to form an oil film, a fluid film. The fluid retaining groove 43 displays its function by flowing to either one of the circumferntial groove 42 and the oil side, but is desirable to flow to both in order to heighten flowability of oil in the fluid retaining groove 43 to improve cooling effect. As a result, the corotating rate of a seal ring and one member is prevented from becoming high, and the deviation of sliding with the other member is prevented so as to improve durability and quality.

Inventor: BANDAI HARUFUMI
IPC: H01G13/00
Filed: 1987-12-07
Abstract: PURPOSE:To derive impact force which electronic chip parts receive by an exact value and to surely prevent the generation of a physical failure of the electronic chip parts caused by impact by providing a mechanical impact force sensor consisting of the same shape as the electronic chip parts and having piezoelectric property. CONSTITUTION:First of all, the mechanical impact force sensor 1 which consists of the same shape as electronic chip parts and has a piezoelectric property is prepared, and the sensor 1 is inserted into the recessed part 10 of a base 6. Subsequently, a measuring terminal 7 and a measuring terminal 8 are moved to the upper part and the lower part, respectively, and both the measuring terminals 7, 8 are allowed to abut on the external electrode 3 of the sensor 1. By impact force in this case, a voltage corresponding to whether the impact force is large or small is generated in the sensor 1. This output voltage is measured and recorded by the oscilloscope of a measuring instrument 9 through the measuring terminals 7, 8. Subsequently, the peak value of the output voltage generated first is converted to impact force by using a piezoelectric constant measured in advance with regard to the sensor 1, and impact force generated due to a fact that the measuring terminals 7, 8 abut on the sensor 1 at the time of measurement is derived. In such a way, the generation of a physical failure of the electronic chip parts caused by an impact can be prevented surely.

Abstract: PURPOSE:To improve the operability of color balance adjustment by adjusting color balance in an RGB state before converting signals of red(R), green(G), and blue(B) into recording colors of yellow(Y), magenta(M), cyan(C), and black (K). CONSTITUTION:Digital data of R, G, and B are supplied to a density conversion part 16, which converts 8-bit data into 6-bit data while a density adjusting circuit 20 adjusts the color balance by the colors.
